Applieati onhfiled June-27,1928, Serial 110.288 .593, and in Germany June 2, 1927.

This invention relates to document hles of the kind, in which the inserted documents are firmlvclampcd by pressing arms eXtending transversely to the niarginal herd er of the documents and, to the fold of the file.

According to the invention, a pair of clips having pressing arms extend along the fold of thefoldcr of the file, and each clip is at its outer end pivoted. transversely to a base, so that it can be swung upwards away from said base.

The two clips when in their d epressed clamping position are interlocked, the pressing arms thereby securely clamping the documents.

It has already been proposed in newspaper holders to employ a pair of aligned rods'for holding newspapers firmly, each of which being pivotediand locked in the depressed position. However, in such newspaper holders the said rods are located along the fold of the newspaper and hold the latter by spikes provided on the rods. Such an arrangement can not therefore be used for document files with widely varying thicknesses of contents.

Anembodiment of the file is illustrated, by way of example, on the accompanying drawin g, in which Fig. 1 is a plan of the file with the parts in the clamping position,

Fig. 2 is a section along. theline IIII of Fig. 1, and

Fig. 3 is alongitudinal section along the liheIIL-III of Fig. 1, the open position of the parts being indicated in dot-dash lines.

A metal base plate a with an upstandmg clamping edge 7) is riveted along one side of the middle fold of and in a cover or folder. At each of the two transverse narrow borders or'cnds of the base plate is a hinge strap 0. Av pair of clamping clips (Z and (Z engage by means of bent ends in the hinge straps 0, so that they are ournalled therein. ing clips (Z, (Z are formed with loops 6 and c, which extend over the clamping edge 7) of the base plate and on clamping serve as prcss ing fingers. The free ends 7 and of the clips are situated opposite one another when I the clips are located in the clamping position. shown in Fig. 1. A. sleeve 9 is siidably mounted on the end of the clip and a bond 72/ (Fi 3) of the clip end i limits the sliding displacement and prevents complete removal of the sleeve. When the ends of the clips 7 and f in the depressed clamping position The clainpare approximately in alignment, the sleeve g is slldably moved with its free end over the free end f of the clip cl, whereby it holds both clips down in the clamping position, as it thereby connects both parts rigidly together; In order to facilitate the slipping over, theextremity of the end f of the clip (Z is slightly bent, as shown at in Fig. 3.

Moreover, conveniently, the sleeve is at its interengagement of the two ends of the clips when of appropriate construction. The clamping clips themselves can be constructed in various forms, in particular as regards the pressing fingers.

I claim 1. In a documentfile, a folder, clip means divided at an intermediate portion of its length extending along the fold of said folder and pivoted at each end transversely to said fold. and a sleeve for interlocking the two portions of said clip means.

2. In a document file, a folder, a pair of clipseach comprising an elongated portion extending'along the fold of the folder and pivoted by means of a transverse journal portion at an end of the folder, anda pressing finger-extending transversely from said elongated portion, and means for interlocking the adjacent ends of said clips.

3. In a document file, a folder, a pair of elips,-cach comprising an elongated port-ion extending along'the fold of the folder, hinge straps on said folder and arranged transverse to said fold, transverse journals formed at the ends of said clips and journaled in said hinge straps. and a pressing tiiuger extending transversely from said elongated portion. and

means for interlocking the adjacent ends of said clips.

- i. In a document file, a folder, a base plate having an upstanding edge and secured to said folder along one side thereof, hinge bearings on said base plate and arranged transverse to said fold at each end of said base plate. a pair of clips, each comprising an elon-' gated portion extending along the fold of jacent ends'of said clips. 5. In a document file, a folder, at base plate,

the folder, a transverse journal received in one of said hinge bearings, and a pressing finger extending transversely from said elongated portion, and means for interloekingthe adhaving an npstandingedge and secured to said'folder along one side thereof, hinge bearings on said base plate and arranged transverse to said told ateaeh end of said base plate, av pair of clips, each compr sing tion of said clips and displacea-ble overthe other portion thereof.

In testimony whereof I have signed my naine to this specification.
